WINDOWV Application filed September This invention relates to pervious window closures more especially to the type known as ventilators and screens.

it is well understood by most persons that windows opened for the admission of air must be provided with some sort of closure, pervious to air but impervious to insects, if Lau'nt'ort and health are to be preserved by those occupying the house in which the windows are placed.

It is also well understood by most persons that the ordinary and well known ventilators or screens commonly sold as an article of commerce have many and serious defects. They are not insect tight; they afford one or more large passageways about the edges for dra'tts; they are insecure to such an extent, that in gusty weather, especially, they rattle and bang to a most irritating extent; they are so placed in the window that a child may knock them out by a light blow, they are ditiicult if not impossible to retain substantially in place partly collapsed when one desires to put his head out of the window to observe something outside, or to hang something outside on a line or on the side of the building; and it is comparatively easy for an intended intruder to collapse the screen from the out side tor the purpose of entering through the window.

A principal object of applicants invention is to provide a window closure of the pervious type which will be insect tight, not only over its ma in surface but also about the edges where the window sash and window frame contact with the closure and at such points will also be dust and grit tight.

A 'lurther object of applicants invention is to provide a closure of the type specified which will, when put in place, ail'ord no opportunity tor intense drafts about its edges.

A further object of applicants invention is to provide a closure of the type specified which will, when in place, be so securely held tha t rattling and banging will not be possible as a result or wind or other vibrations; that a child an. not knock it out of the window by such a "Force as a child would be likely to exert and. would [ind it difficult toremove in any event; that same may be retained quite seciu'cly in place partially collapsed and that same would offer even more dilliculty to an intended intruder to remove from the outside oil the window.

Other objects and advantages will appear CLOSURE.

In describing the particular physical embodiment and modifications thereof, selected to illustrate the invention, reference will be had to the accompanying drawings and the several views therein, in which similar charactors of reference designate like parts throughout the several. views and in which Figure 1 is a :lragmentary elevational view oi a window frame and sash, together with a closure embodying applicants invent-ion in place therein, viewed from the inside; F 2, is a cross sectional view on the plane indicated by the line II-II of Fig. 1, viewed in the direction oi' the arrows at the ends of the line; Fig. 3 a cross sectional view on the plane indicated bythe line III-III of Fig. 1, viewed in the direction of the arrows at the ends of the line; Fig. l, is a fragmentary perspective view, partly in section illustrating among other claims an improved fastening or connecting means provided. by applicant; Fig. 5, is a detail 'lragn'ientary cross sectional plan view of a window frame or casing and applicants closure illustrating a means provided by applicant tor fastening or retaining the lower portion of the closure in place; Fig. (i, is a detail. fragmentary cross sectional elevational. view of a. window lrame or casing and applicauts closure, illustrating by another view the same fastening or retainin means as shown by Fig. 5; Fig. 7, is a fragmentary cross sectional. view illustrating a. modification of al nalicants main fastening or connecting means. Fig. 8, illustrates in cross-sectional plan view the cmistruction o'l the frame ol. applicants closure. Fig. 9, is a fragmentary cross sectional view illustrating a modification of applicants main Fastening or connecting means.

In Figure 1., numeral. 1 designates the lower rail of the window sash. 2 designates the inside finish of the window 'lrai'ne. 3 is moulding forming the inside stop for the window sash. 4:, best shown in Fig. 2. designates the parting strip. 5 the window sash channel for the inside window sash. 6, best shown in Fig. 3, designates the window sill or surface against which the lower rail oi. the inner sash rests when closed. This sill slopes gen.- tly outward as shown in Fig. 3.

one plane.

Applicants closure for the space formed by the window sash, the bottom rail of which is designated 1, when raised is essentially a telescoping frame corresponding with the ordinary and well known telescoping frame now commonly sold as a window screen. Ap plicants frame is so made however, for a reason to be later explained, so that each side thereof lies in a plane. This is best shown by Fig. 8. The vertical end posts 7 are each made the depth of one section or leaf of the frame, as the distance between the arrows 8, and also in addition the depth of the other leaf, that is, each end post is double the thickness of each top or bottom rail. of each leaf or section. By such construction the surfaces 11 and 12 lie in one plane parallel to the median vertical plane of the frame and surfaces 9 and likewise lie in The bottom and top rails are held together in the usual manner in sliding relation by having a dovetail groove formed in each in which the double doyetail spline 13, best shown in Fig. is inserted. By so making the frame the necessity of twisting the frame out of alignment when placing it in a window is avoided.

By constructing the frame of applicants closure in the manner described, the end posts, when the frame is inserted in a window, may be caused to rest tightly against the outside surface of the mouldings 3 as each end ofthe window and so perfectly close the same to the entrance of insects or strong and intense drafts.

The two rails at the bottom of applicants frame are constructed with a somewhat sharp lower corner, as 14;, best shown in Fig. 3. This sharp lower corner may extend the whole length of the rail or only a portion thereof. This somewhat sharp edge or protuberance serves to prevent the frame from sliding down the gentle slope of the window sill, and on account of friction being reduced to a minimum, this construction permits of easy telescoping of the sections when in place in a window.

Each of the top rails of the section has fitted thereto either integrally or as a separate piece the shoulder or partial arcuate members, as 15 and 16. These members are formed as shown in Figs. 3 and 1 to interfit and slide with the sections one on or within the other. The arcuate or shoulder of the sliding member 15 is attached to one section as viewed in Fig. 1, and the shoulder member their top surfaces. By means of the shoulder members 15 and 16 the only remaining space between the window sash or window frame and applicants frame is closed so that insects and drafts are avoided.

The shoulder members 15 and 16 also atford a ready means for determining whether the screen is in correct position in the window, because in the dark one may readily move a. hand over the lower rail of the sash toward the frame. If the shoulder is proscnt all along the lower edge of the sash the frame is properly in place.

In order to more securely hold the frame in place a series of one or more holes 19, are formed in the shoulder member 15 and a hole or cavity 20 in the window sash and a headed pin 21 is provided, which is placed, in one of the holes 19 most closely adjacent the end of shoulder member 16 and which is also in line with the hole or cavity in the window sash. By this means the telescoping of the frame is substantially prevented by anyone except a person on the inside of the window and even then unless the pin 21 is first withdrawn, so that a small child could not in general reach the pin 21. and so could not collapse the frame with a purpose of climbing out of the window and pin penetrating window sash prevents child from raising window and climbing over screens.

By providing the shoulder members 15 16, each extending the full length of the section to which attached except for a short dis tance atthe ends as shown in Fig. 1, at 22 and 23 the space normally open is closed but also in addition the frame is securely fastened in place so that it cannot sway and rattle and bang. It is held from inward movement by the contact between surfaces 9 and 10 and the mouldings 3 and. from outward moy'cmentby shoulders 15 and 16 hearing a gainst rail 1. The cut away portions 22 and 23 are just suflicient so that the end of shoulder 15 bears against the side of moulding 3 on one side of the window as viewed in Figs. 1 and 2, and the end of shoulder 16 bears against moulding 3 on the opposite side. lly this means a slight crevice which would otherwise occur at 22 and 23 is prevented, and the frame may be properly inserted in any window no matter how tight the contact between the window sash and the mouldings 3. The lower edge of the bottom rail bears tightly and against the sill 6 and is prevented from slid--- ing out by the sharp corner or rotuberanccs 1 1.

An additional construction to prevent the lower portion of the frame from i'noving outwardly is provided by placing small dowel pin in one or both sections. This is shown in Figs. 5 and 6 in which the dowel pin in the left hand section is shown and designated 24, placed to enter a cavity 25 formed in the window frame. These dowel pins may be Ill) lii

used with or in addition to or an alternative for the sharp corner or protuberance 1-1.

As the opposite top section of the sliding frame members has contact with the window rail at three points, due to the arcuate construction of the shoulder there is a minimum resistance to the movement of the sliding members so that it may be easily collapsed or tel-escoped while the frame is in place for the purpose of getting at the outside.

hilembers and 16 as shown in Fig. 3, may be constructed in many ways, two alternate types of which are illustrated and shown in Figs. 7 or 9.

The purpose of any of the various forms of construction of this frame or device is for suitable adaption of a material Fig 4, which may be of any suitable material, which an be used as a ventilator or screenmp3.

The construction of this frame permits the adoption of material to be used with appli cants invention for any desired protection such as insects, drafts, or any other elements not wanted. Its principal object is the security against rattling or banging and the possible onslaught of small children, cats, dogs, etc, and the fact that applicanhs device is easy to put in or take out or nrrtially collapse while in place to give access to the outside and is a more definite security against the attempts of intruders than the materials now used for screening or ventilating.

The frame described may be constructed of various materials, wood or metal being preferred.

Althrmgh applicant has illustrated and described a )2L1tl()1ll2tl' physical embodiment of his invention and some modifications thereof and ez-lplained the principle, construction and modification of operation thereof, nevertheless, the forms illustrated and described are merely illustrative and do not exhaust the possible physical embodiment of means underlying the invention.
